To all W/ofm 'it 97mg," concern.'

Be it known that l. FREDERICK C. Cosco, a citizen of the United States. residing at Columbus. in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Electric Locomotives and Cable-Feeling lllechanism, of which the following is a specification, reference being had therein to the accompanying drawings. v l

This invention relates to electric locomotives and more particularly to means adapted to rotate the cable reel ofya locomotive in one direction irrespective of whether the locomotive is moving forward or backward so as to effect the proper winding of the cable upon the reel.

The principal object of the invention is to provide. in connection with an electric locomotive a cable reeling mechanism which operates automatically to drive the reel in one direction of rotation irrespective of the direction in which the said locomotive is trav.

cling, and which will be positively operated at all times independently of the direction of rotation of the track wheels of the locomotive or their axles.

Further objects of my invention will be apparent from the description of a device embodying it, which. for the purpose of illustration, l have presented in this application.

Figure l is a side elevation of a portion of a locomotive having a cable reel and cable reel driving mechanism embodying my improvements. Fig. 2 is a plan view of the locomotive. Fig. i is a side elevation partly in section` show-ing the motor, the reel and the power transmitting mechanism interposed between the motor and the reel. Fig. l is a central vertical longitudinal section through the reel and associated parts. Fig. 5 is a section of the ratchet and pawl mechanism taken on the line 5--5 of Fig. 3. Fig. 6 is a side elevation partly in section, showing one of the pawl-carrying gears of pawls being shown in position therein.l Fig. 7 is a section on the line 7--7 of Fig. 6, the pawls being removed. Fig. 8 is a side elevation partly in section, showing one of the driving sprockets provided with ratchet recesses therein, and Fig. 9 is a section on the line 9`9 Fig. 8. Figs. l0 to 15 show details.

ln the drawings 1 respresents an electric locomotive as an entirety, 2 an axle at one end thereof, 3 car wheels on said axle, l a motor mounted in the car frame in any suitable manner, 5 a cable reel arranged both to pay out and to wind up a flexible cable G by means of which electricity may be conducted to the motor l on the car when desired. 4l indicates a trolley mechanism also adapted to conduct electric current to the motor on the car. The motor pinion 4Q meshes with the gear wheel 4l on the axle 2, and in this way the motion ofthe motor is transmitted to the gear wheels to propel the locomotive. As to the elements above referred to, they may be of any suitable and well known type, and for this reason I have not deemed it necessary to describe them in detail. I

For purposes of illustration I have shown va reel mechanism similar to that shown in Patent .95st,475. issued April l2, 19M), to Frank L. Sessions. In the construction shown the cable reel 5 is carried by a reel shaft 5 mounted in suitable bearings in the standards 5 on the frame of the locomotive, the reel preferably being rigidly secured to the shaft.

T is a sprocket wheel loosely mounted on the shaft 5 and through which rotary motion may be imparted for rotating the cable reel 5. Preferably this sprocket wheel has formed integrally with it or secured to it one element of a friction clutch 8, the other element of which is movable relative thereto and is splined to the shaft 5. 8 are springs adapted normally to press the elements of the Ifriction clutch into operative engagement with each other, and 9 is an operating lever connected to the movable element on the clutch shaft 5. At the opposite end of the 'reel from this driving mechanism is arranged a friction retarding device indicated as an entirety by 10. Thisdevice is adapted to operate or j during the paying olf of sistea friction plate 10. carried by the reePand a cooperating plate or disk 10@ loosely mounted upon the shaft 5 and held normally in engagement with the plate 10 ,a by the springs 10b.. The Ilate ordisk 10a carries ratchet teeth 10,c w ich are adapted to be engaged Vby -a pawl 10El carried by an arm 5b secured to the` adjacent standard 5a. This pawl rides over the ratchet teeth when the reel is rotated,V to windv up the cable thereon, but engages with the teeth and holds the disk or plate 1 0a stationary when the reel is rotated in the opposite direction to pay, outV the cable. Duringothis paying oi of the cable from the reel the friction retarding device 10 will consequently op-, crate to oppose the rotation of the-reel.

The cable 6 is preferably led inward through the periphery of the reel and thence out through the hollowed end of the shaft A5', and is electrically connected to the electric collector at 1l. From thence the current is conducted tothe motor by the conductor 11.

12 indicates as an entirety the mechanism by'x'neans'of which rotary motion always in oney direction. 4is imparted from thel motor to l the sprocket wheel 7 and hence to the reel tive.

The -hfnge pins 15 are preferablyheld- 17 indicates a .sprocket wheel loosely -f mounted on thehub, 1350i the gear wheel 13. The inner cylindrical surface of this sprocket wheel 17 is recessed at regular i`ntervals as indicated at 17 these recesses be ing adapted to receive the lpawls 14. Each of the recesses has 'at one end a radial wall- 17a which serves as a ratchet tooth or sur: g face with which the Ifree end of one of the pawls '11 will engage When the gear 1341i@ tatesin one direction and will thus effect the A rotation of the sprocket 17. At its opposite l end each recess has a non-radial. wall 17" over which the pawls 14 are adapted'to ride without engaging the sprocket. 17 in such manner as to transmit power thereto for opn 1 erating it. In other words, I have simply interposed between the gear wheel 13` and the sprocket wheel 17 a ratchet and pawl mechanism adapted to operate to effect the rotation together of the said Wheels in-'on'el direction, while permitting the gear wheel 13 to rotate relatively to the said sprocket vvtending-I therefrom in the samedirectionas' and parallel to the extended end @fof theA armature shaft. 19 is a'gear"wheelloosely y mpunted on said shaft 18. This r Wheelv The motor 4 isf preferablyv varranged is identically-similar in structure detail"l to 'looselymounted upon4 it a' sprocket 2(7)" which is similar in every particular to the sprocket 17 carried by the 'gear 13. Ratchet and pawl mechanism indicated as an entirety by 21 is Ainterposed between the gear wheel 19 and theI sprocket wheel 20 andas itissimilar in 'every particular to the ratchet 'and pm vl mechanism betweenv the' gear Wheel 13 and thesprocket wheel 17, it is not necessary to further' describe it. ,i

Assuming that the locomotive has reached a pointjrom which it' is desired toV supply current to the locomotive through the cable trolley mechanism, the locomotive is nearest to the saidy fixed point and the cable is' to be paid ofi from 6 insteadI of throughltheg; and that the reel end of he :dfi dbg-1mi jemand? i ,im ivo di' 'i however, i, i@

- This traveler comprises a frame 29 adapted when the' @atie is te be i' adj acent standard 5a pair of longitudinally mountedrollers 29a and a pair of. t'ransversely mounted rollers 29". lThe rollers of each 'of these pairs of rollers are adaptedto receive between them and to guide the cable 6.'

aid loff .from and wound up upon the reel .rom the reel end ofthe locomotive, it is desirable to have the cable spooling and guiding mechanism arl.

ranged as shown in full lines in Fig. 3, so that ythe traveler 29 for guiding the cable 'onto the reel. will be in front of the reel. vTo hold the cable spooling and guiding mechanism in this position I have provided ,brackets 32 arranged at either side of the reel supporting structure, eachlsecured to an and each adapted to engage with and support one of thebearing plates 24". When it is necessary to pay out and reel up the cable from the operators end of the locomotive, the cable spooling and -guiding mechanism may be swung to the position indicated in dotted lines in. Fig. 3,'in

which case the cable guiding traveler is still infront of the reel when the direction of travelof the reel is cor1sideredr-zFor` main-- taining thespooling and guiding mechanism in this position I have provided brackets 33 each arranged at one end of the reel supporting frame, standard 5* and-,each'adapted to engage and su port one ofthe bearing plates 24".

he transversely arranged guide and supporting rollers carried by the traveler frame 29 are so arranged that one of them will -support the flexible cable when the spooling an While the other will support'the cable when the said mechanism is in its other position.

Iam awaref'of4 the fact that it has been proposed to construct a cable reeling mechanism for an electriclocomotive in which mechanism was provided for effecting the traveler adaptedl to'travel to and fro alongsaid double threadapted to engage the walls off the'.

I which the driving element each secured to the adjacent l in a direction tending to wind -up the reel,

idind mechanism 1s in one osition which end of the locomotive was traveling-in advance toward the paid out cable. In this suggested construction, however, it was necessary, each time that a change was made to pay out and reel up the cable either from the I reel end of the locomotive or fronrthe-,operators end of the locomotive, for the operatorl Q' to manually throw into or out of operation one or another of two trains of power transmitting devices, each of whichfwas adapted to rotate the reel in one direction only. 4In the event of the operator forgetting to make these changes in the transmission'fsystem at the required time, the reelingl`mechanism would fail tov operate` as desired and great danger resulted of breaking or seriously injuring theflexible cable.

I believe that I am the first to devise a mechanism which automatically operates to effect the rotation of the reel always in one direction irrespective of the direction of rotation of the rotary element from which power is taken to drive the said reel. i The friction retarding mechanism 10 is adapted under all ordinary circumstances to automatically control the reel in its rotation in unwinding direction. And under most clrcumstances. it will be found best to manu ally disconnectv the clutch mechanism at 8,.

But while-this is the ordinary operation of the mechanism of my invention, it is desirable to be able to manually control theun-V winding of the reel by means supplementary to the automatic friction yretardin vice 1.0. This automatic brake l0 apphesa`v braking 'effect of predetermined amount and it often lhappens that' because deceleration of the locomotive,

automatic brake 10 additional braking means mustbe brought into action by the op-r erator.V y expedient of throwing the clutch into op'- erative position of the rapid'` or because of the improper or'defective operation of the K This isA accomplished 'by the simple Yduring the unwinding of. f

the reel. The lever '9 controls the degree off? pressure eisting between the elements of the clutch- A 8 and act as a brake to retard the ldriven element.

consequently the extenttov *l of the clutch wlll'lll Because the sprocket wheel 7 always rotates the elements of the clutch S will rotate in opposite directions when the reel is rotataingin the unwinding direction. -As a result the clutch element which is connected with the motor constantly tends to reverse the rotay tion of the reel and, therefore, effectively y comes slack, `thisv lconstantly rotating clutch element at once acts to rewind 'the cable and A.

restore the proper tension.
